The main event of UFC 228 on Sept. 8 in Dallas will be a welterweight title fight between champion Tyron Woodley and Darren Till. ESPN.com first reported the bout Tuesday, and UFC officials later confirmed it to Sporting News.

It was expected that Woodley would face interim titleholder Colby Covington in his return to the Octagon, with UFC 228 being the desired spot, but sources told SN that Covington would be unable to fight on that date because he had nasal surgery Tuesday. The earliest he would be able to return is in November or December.

UFC president Dana White told ESPN that Covington will be stripped of the title when Woodley vs. Till begins.

Since winning the strap at UFC 201 in July 2016 from Robbie Lawler, Woodley (18-3-1) has made three consecutive defenses. He has defeated Stephen Thompson twice and, most recently, Demian Maia at UFC 214. Overall, Woodley will go into UFC 228 unbeaten in his last six fights.

Woodley had surgery after the Maia fight to repair a torn labrum.

Till (17-0-1) made MMA fans take notice when he scored a first-round TKO victory over Donald Cerrone at UFC Gdansk in October. The 25-year-old solidified a title shot by defeating Thompson via a close unanimous decision at UFC Liverpool in May. Till missed weight by three pounds the day before the fight.
